Biography
Shi Shen, also known as Shi Shenfu, was a Chinese astronomer and astrologer from the 4th century BC in the State of Wei. This state came about after the breakup of the State of Jin during the Warring States period. He is considered one of the key astronomical observers in ancient China, and his work was foundational for Chinese observational astronomy for many years. Although the exact dates of his birth and death are unclear, records confirm he was active in the 4th century BC, making him an important figure during a peak time of Chinese intellectual growth.
Before Fame
Details about Shi Shen's early life are not available in historical records, which is typical for people of his time. What's known is that he came from the intellectual scene of 4th century BC China, when the Warring States were not only clashing in wars but also developing expertise and knowledge. Court jobs for astronomers and diviners offered both resources and reasons to study the skies systematically. Shi Shen likely trained in a tradition of sky-watching that had been part of Chinese court culture for centuries. He built on earlier records and methods, refining and expanding them into his own systematic catalog.
